TRAINOR SPRING FRAME SEAT Filed March. 8, 1935Inveno (E/Md WWI/70A- Patented July 2, 1935 a 2,006,421 v I srme ras msun Felix rm'inei," l N' wcastle, assign er Trainer Nationalspringcompany Newoastle l andiparticularlyto. a novel typeofehairfior-the like wherein all of the supporting-members are formed ofspring material toproduc'e a yielding. 5 flexible structure fittingitself to the occupant with a suitable degree off re'silieney and[provid ingthe utmost comfort'. Another; advantage of my invention isthat it may be incorporated in a number -of designs gi'vinga verypleasingand 10 striking effect suitable to-be madeup'in -varying 7colors *and patterns A further, advantage is found in the'fact thatbyreason ot the allmetal-f" is extremely durable and mayeven'be'subjected' 15 to out of-door use without-appreciabledamage.

These and other objectsand advantages of my invention wil l becomeapparent to those versed in theart in the following description whichismade 29 wherein embodyingmy invention:

Referring first to that 'formfshownin tFi'gsbl' may: employ a" pair ofrunners l 0 and l I,, each having a major' length thereof normally horizontally disposed.

The seatZS and backjt may beef usualrigidstructure with resilient upholstery mereem'so that the distancebetween. the bar 23 and the rear hingeline of the; seat 25 c withtheback 'fl ismaintained under load.

Now when;the.; seat or thus described l c up ig flw l om l -pos t on: as

indicated by-the dash lines in Figg 4, depending,

of course; uponthe weight of the occupantand to. what degree/the.Occupant, desires to rock; It

is'to be considered that the dash line position is merely illustrativeand is not to be considered as the absolute P ition variousmemberswillassume. 7 vlllfl'ien the occupant sits down andleems backagainst thelhackle, the side members l2 and Ilwill tend to roll back along theirrunners while at the same; time the portions l6 and 2| 1 will assumesharper curves therebypermitting a the'balck supports-20 will permita-fslightfiexing rearwardly thereof so as to permit ther' back to assumea more inclinedposition-.-"The hinging of 4 the seat and back permitsassumed new. positions as indicated soil-that the seatand back willreadily accommodate themselves to theoccupants position. As-the membersand Bare thusdeformedunder load, the forward ends of tend to lift. Thusevery supporting member outside of the seat and back may be flexed anddeformed somewhat to accommodate itself readily to the load and topermit an easy rocking of the chair. As a matter of finish and toprevent damage to the floor, the forward ends of the runners Ill and IIare preferably turned upwardly somewhat onithecurvesii and there'ar ends'are' provided withturned up or rolled 'over ends.

In the form of the invention shown in Fig. 2,

the supporting structure remains exactly the same as that describedabove with the exception that the s L5 25 and back 26 are replaced witha length of fabric 21 hung between the bar 23 and the bar 24. Also forthe sake of changed appearance, additional blocks 28 are placed on topof the arm rest portions I8. I

In the form shown in Fig. 3, the same support combined canvas seatandback 29 isemployed, in this case havingthehdditloh theretol ofanupholstered head rIestjIl and a seat cushion 3|.

Another modification from thatshownirithi: two.

formspreviously described is that onthe runners l0 and II Iadd asiperimposedplate 32 ease to have the rear end'of' that plate}! upwardlynear the lrear 'en'daway from the runner and thence sharply'idownwardlyto join. with and be secured to'the runner at its end.

aws thus added to pro vide anincreasing resalience tot-he rocking backor the sidefmembfers. l2 and I3 as their portions 211011 into contacttherewith. Of course, the runners i0 andfl ifmay be omitted entirely inthis form if desired, so that the bearing plates 3; then ny the membersno and Malone.

In any thejformsabovedescribedi I achieve an extremely "comfortablechairwhich will settle back to accommodate the occupantwithout. any

tendency to pitch himiorward." The curves of the various members 'are sopositioned andplaced as indicated as to prevent such pitching and at,

the same time prevent too'niuch ofithe springmembers' I contact with therunner over-a forward portion only thereof; the upper' ends of said legsbeing curved aroundtoward'each other to 'form' a re-- silient tietherebetween; a resilient back support" member extending from said tieandturned upwardiy; a seat bar interconnecting said front} legs; abackbar interconnecting said back support members; and a seat carried bysaid two While I havehereinshown-and described my invention in the formsas now best known to me, it is obvious thatstructurallchanges may bemade without departing from i the spirit of the invention, and I;therefore do not'desire to those precise forms beyond the as maybe'imposediby the following I 1.
